KX3 drifting downwards

Hello to everyone .

I have a brandnew KX3 and have the following problem .

Using the KX3 in SSB or CW mode then he start to drift downwards with 1Khz almost every time when the KX3 going in TX mode (push the mic or footswith or the keyer ) .

In Data mode there is no problem ..using wsjt-x

Configuration :

1. Power Supply DM-330MVE = 13,8V dropping in TX to 13,6 V

2. KX3 10242 connected with all original cable from Elecraft to the power supply and PC

On FT8 mode freq : 5.357

Power : 0,9 watt on kx3

Start at : Osc = 27 ° Celsius

After 15 min : 31 °

After 60 min : 34 °

No drifiting !!!!!!!!!

On FT8 mode freq : 14.074

Power : 1 watt on kx3

Start at : Osc = 34° Celsius

After 15 min : 35 °

After 60 min : 37 °

No drifiting !!!!!!!!!!!

On SSB / CW mode freq : 14.290

Power : 1watt on kx3

Start at : Osc = 29° Celsius

After 15 min : 33 °

After 30 min : 35 °

Drifiting downward !!!!!!!!!!!!!!!!!

My KX3 is drifting when I use USB or CW mode NOT on FT8 mode with the same configuration .

1. He start to drift downward every time when go to TX ( push the PTT ( or foot ) switch ) or the keyer .

2. Blocking VFO A make no different .

3. When I work SPLIT in SSB VFO A is drifting downwards and VFO B stay stable !!!!!!!!!!!!!!

When I have a pileup and qso's going very fast I must correct continuously adjust the frequency with the dial knob

It seem that this NOT a temperature problem , does anyone have the same problem

Re: KX3 drifting downwards

What is your menu setting for MIC BTN? If it is set to UP.DN and used with
a non Elecraft mic without up/down buttons, it may trigger the frequency
change. Try changing the setting to PTT.

Yep. That's what worked for me, thanks to an earlier poster.

I don’t have manual or radio handy so can’t tell you exact setting, but ... go into menu and disable mic up down button function. See if that works. It worked for me
